Technical Field

[0001] The invention relates to the technical field of fire prevention and early warning, and in particular to a forest fire prevention and early warning device for forestry in mountainous areas. Background Art

[0002] Forest fire prevention is always a major focus of ecological protection today, because it covers a large area and has a lot of ignitable materials. A small spark may cause a fire. Conventional forest fire early warning methods are to use manual monitoring such as ground patrols and lookout monitoring to monitor the fire. This method is not only labor-intensive but also has poor early warning effects. With the continuous development of technology, forest fire early warning technologies are becoming more and more diverse. Commonly used forest fire early warning methods include: remote wireless monitoring systems based on wireless / wired network technology, drone cruises, satellite remote sensing monitoring and other technologies. Compared with drone cruises and satellite remote sensing monitoring methods, wireless monitoring systems have the advantages of low long-term operating costs, large-area, continuous monitoring, and less impact from weather.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] For example, see Figures 1 to 9 A forest fire early warning device for mountain forestry includes a support rod 1, a camera unit and a control unit are arranged on the support rod 1, the camera unit includes a monitor 2, the control unit includes a PLC controller 3, a protection mechanism is arranged on one side of the support rod 1, and the protection mechanism includes a shell 4, a protection chamber 401 is arranged in the shell 4, and a first opening 402 is arranged on the top of the protection chamber 401; A base 5 is provided at the bottom of the support rod 1, and the support rod 1 and the base 5 are rotatably connected. A baffle 6 is slidably connected to the base 5, and an electric push rod 7 for adjusting the position of the baffle 6 is provided on one side of the base 5. A cover plate 8 is provided on the support rod 1.

[0029] The camera unit also includes a connecting seat 24, which is rotatably connected to the support rod 1, and a cross bar 25 is provided on the connecting seat 24. The monitor 2 is installed on the cross bar 25. The cover plate 8 is detachably connected to the cross bar 25 by bolts. The support rod 1 is provided with a driving motor 26 for driving the connecting seat 24 to rotate.

[0030] The control unit also includes a protective shell 27, in which a GPRS wireless terminal 28 is arranged, and a temperature and humidity sensor 29 is arranged on the outside of the protective shell 27. The PLC controller 3 is located in the protective shell 27, and the data access end of the PLC controller 3 is connected to the temperature and humidity sensor 29 and the data output end of the monitor 2 by wires, and the data output end of the PLC controller 3 is connected to the signal receiving end of the GPRS wireless terminal 28 by wires.

[0031] The present application provides an angle-adjustable support rod 1, a camera unit, and a control unit. A cross bar 25 is provided on the support rod 1. The camera unit and the control unit are both mounted on the cross bar 25. When a fire occurs, the support rod 1 flips over, and the end of the support rod 1 with the cross bar 25 tilts toward the ground. Then, the cross bar 25 is inserted into the protective chamber 401 on the housing 4. During normal use, the housing 4 can be completely or half-buried in the soil. In this way, in the event of a fire, the housing 4 with the protective chamber 401 can protect the equipment on the cross bar 25. Specifically, a baffle 6 for limiting the support rod 1 is provided at the base 5. The support rod 1 can be tilted at a predetermined angle by simply pulling out the baffle 6. The camera unit includes a monitor 2. The monitor 2 used in this application is a hemispherical infrared thermal imager. The monitor 2 itself has the function of self-rotation. At the same time, the cross bar 25 used to install the monitor 2 can also rotate under the drive of the connecting seat 24, and there are few blind spots for monitoring. The control unit includes a PLC controller 3 and a GPRS wireless terminal 28. The monitor 2 takes video of the area surrounding the support rod 1, and then the PLC controller 3 sends the collected video information to the host computer through the GPRS wireless terminal 28, so as to achieve a remote monitoring and early warning function. The temperature and humidity sensors The device 29 can monitor the ambient temperature and humidity around the support rod 1. When a fire occurs around the support rod 1, the operator remotely controls the electric push rod 7 and the drive motor 26 through the PLC controller 3 and the GPRS wireless terminal 28, and adjusts the position of the cross bar 25 through the drive motor 26 so that it can enter the protection room 401 after the support rod 1 falls over. The baffle 6 moves under the drive of the electric push rod 7. After the baffle 6 is lost, the support rod 1 falls over, and then the cross bar 25 enters the protection room 401. In order to improve the protection effect, a cover plate 8 that matches the first opening 402 is also provided on the support rod 1. When one end of the cross bar 25 with the equipment enters the protection room 401, the first opening 402 can be covered by the cover plate 8.

[0032] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9A water storage bag 9 is provided on one side of the protection chamber 401, a joint 901 for communicating with the protection chamber 401 is provided on the lower side of the water storage bag 9, and a protrusion 902 is provided on the upper end of the water storage bag 9, and a water volume regulating mechanism for regulating the joint 901 is provided in the protection chamber 401.

[0033] The water volume regulating mechanism includes an end cover 10 installed on the joint 901, a sliding block 11 is provided on one side of the end cover 10, the sliding block 11 is slidably connected to the housing 4, and a cutting knife 12 is provided at one end of the sliding block 11 close to the end cover 10, and a slope is provided at the other end of the sliding block 11.

[0034] In order to further improve the protection effect, the present application also sets a water storage bag 9 on one side of the protection chamber 401. Correspondingly, a water volume regulating mechanism is also set in the outer shell 4. The joint 901 can be adjusted by the water volume regulating mechanism, so that the water in the water storage bag 9 can be put into the protection chamber 401, so that the equipment on the cross bar 25 can be immersed in water, and the equipment can be better protected in the event of a fire. Specifically, the water volume regulating mechanism includes an end cover 10, and a sliding block 11 is provided on one side of the end cover 10. When the cross bar 25 enters the outer shell 4, the membrane breaking rod 19 on the cross bar 25 will conflict with the inclined surface on the sliding block 11. Under the push of the membrane breaking rod 19, the sliding block 11 drives the cutting knife 12 to move, and the end cover 10 can be destroyed by the cutting knife 12. When the end cover 10 is destroyed, the water in the water storage bag 9 will enter the protection chamber 401, thereby having an effect of cooling the equipment, greatly improving the protection effect of the protection mechanism.

[0035] It should be noted that in order to prevent the equipment at the camera unit and the control unit from being damaged due to water ingress, the equipment at the camera unit and the control unit needs to be waterproofed.

[0036] Example 3: This example is an explanation based on Example 1. For details, please refer to Fig. 9 This embodiment also discloses another water volume regulating mechanism, which includes a valve body 13 installed on a joint 901, a valve stem 14 is provided in the valve body 13, and the valve stem 14 is elastically connected to the valve body 13 through a limit spring 15, and a seesaw 16 is provided at the bottom of the protective chamber 401, the seesaw 16 is rotatably connected to the housing 4, and one end of the seesaw 16 is in contact with the valve stem 14.

[0037] The valve stem 14 on the valve body 13 is connected to the valve body 13 through a limit spring 15. Under normal conditions, the valve stem 14 is in a closed state. When the cross bar 25 enters the protection chamber 401, the membrane rupturing rod 19 on the cross bar 25 contacts the seesaw 16, and then the seesaw 16 deflects, and its other end contacts the valve stem 14. Pushed by the seesaw 16, the valve stem 14 rises. At this time, the valve body 13 is in an open state, and the water in the water storage bag 9 enters the protection chamber 401.

[0038] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 , a fixing plate 17 for sealing the first opening 402 is provided on the upper side of the housing 4, the fixing plate 17 is detachably connected to the housing 4 by screws, and a sealing film 18 is provided on the fixing plate 17; A membrane-breaking rod 19 is provided on one side of the monitoring instrument 2 . A blade 20 is provided on the membrane-breaking rod 19 . The membrane-breaking rod 19 is fixed to one end of a cross bar 25 .

[0039] A sealing mechanism is provided on the upper side of the shell 4, and the sealing mechanism includes a movable plate 21, the movable plate 21 is slidably connected to the shell 4, one end of the movable plate 21 is provided with a slope, and the other end of the movable plate 21 is conical, and a sub-plate 801 is symmetrically provided on the cover plate 8, and the sub-plate 801 is elastically connected to the cover plate 8 through a rebound spring 802.

[0040] A storage cavity 403 for storing the water storage bag 9 is provided in the housing 4 , and a second opening 404 for the protrusion 902 to extend out is provided at the top of the storage cavity 403 . The protrusion 902 is a hollow structure, and one end of the protrusion 902 is connected to the water storage bag 9 .

[0041] An adjusting plate 22 is disposed at the lower end of the storage cavity 403 , and the adjusting plate 22 is elastically connected to the storage cavity 403 via a supporting spring 30 , and a push rod 23 is disposed at the upper end of the adjusting plate 22 .

[0042] In order to prevent fallen leaves, dust and other debris from entering the protection chamber 401 during daily use, the present technical solution is further provided with a fixing plate 17 at the outer shell 4, and the fixing plate 17 is detachable. A sealing film 18 is provided on the fixing plate 17, and the first opening 402 can be sealed by the sealing film 18. Correspondingly, a film-breaking rod 19 is provided on the cross bar 25, and a blade 20 is provided on the film-breaking rod 19. The sealing film 18 can be cut by the blade 20 during the tipping process of the cross bar 25, so that the cross bar 25 and the equipment thereon can easily enter the protection chamber 401. In the present technical solution, the cross bar 25 and other equipment will not completely destroy the sealing film 18 after entering the protection chamber 401. Therefore, the sealing film 18 in the present solution can not only prevent debris from entering the protection chamber 401, but also cooperate with the cover plate 8 to strengthen the sealing effect of the protection chamber 401 after the cross bar 25 enters the protection chamber 401.

[0043] When the support rod 1 is deflected, its end will contact the housing 4. In order to reduce the impact of the impact on the equipment on the cross bar 25, the present application improves the housing 4 and the water storage bag 9. A protrusion 902 is provided on the water storage bag 9. Correspondingly, a second opening 404 for the protrusion 902 to extend is provided at the top of the storage cavity 403. That is to say, the protrusion 902 usually protrudes from the housing 4. In this way, when the support rod 1 is tilted, its end will contact the protrusion 902. Water is also stored in the protrusion 902. In this way, water can be discharged through the protrusion 90 2 can play a buffering role in the process of the support rod 1 being tilted, reducing the impact of the impact force on the equipment. It should be noted that the existence of the protrusion 902 will not affect the linkage between the membrane-breaking rod 19 and the water volume regulating mechanism. When the water volume regulating mechanism is turned on, the water in the water storage bag 9 enters the protection chamber 401, and the water in the protrusion 902 flows out. Under the pressure of the support rod 1, it will gradually shrink into the housing 4, and finally the support rod 1 will reach the preset position. At this time, the cover plate 8 can play a sealing effect on the protection chamber 401; In order to reduce the probability of collision between the cross bar 25 and the shell 4 during the tipping process, the first opening 402 is larger than the equipment on the cross bar 25, but this will result in a poor sealing effect of the cover plate 8 on the first opening 402. In order to solve the above problem, the technical solution improves the cover plate 8, and a movable sub-plate 801 is provided on the cover plate 8. The sub-plate 801 is elastically connected to the cover plate 8 through a rebound spring 802, and one end of the sub-plate 801 protrudes from the cover plate 8. Correspondingly, a movable movable plate 21 is provided on the shell 4, and an adjusting plate 22 for adjusting the movable plate 21 is also provided on the lower side of the shell 4. The adjusting plate 22 is elastically connected to the storage chamber 403 through a supporting spring 30, and the water storage bag 9 is placed on the adjusting plate 22. When the water storage bag 9 is full of water, its weight is relatively large. Under the action of the water storage bag 9, the adjusting plate 22 is located in a low position. At this time, the support The support spring 30 is in a state of storing force. As the water is discharged, the weight of the water storage bag 9 becomes lighter and lighter. At this time, the adjustment plate 22 will move upward under the push of the support spring 30. A push rod 23 is provided on the adjustment plate 22. One end of the push rod 23 contacts the end of the movable plate 21 with an inclined surface. Under the push of the push rod 23, the movable plate 21 slides out of the shell 4. During this process, the end of the movable plate 21 with a conical tip is inserted into the gap between the two sub-plates 801. Under the push of the movable plate 21, the sub-plate 801 overcomes the resistance of the rebound spring 802 and moves until the sub-plate 801 contacts the protrusions on both sides of the shell 4. In this way, the gap between the cover plate 8 and the shell 4 can be closed from multiple angles through the movable plate 21 and the sub-plate 801, which further improves the sealing effect of the cover plate 8 on the protective chamber 401, and also indirectly improves the protective effect of the shell 4 on the equipment in the protective chamber 401. It should be noted that, in order to ensure the stability of the movable plate 21, a spring may be provided between the movable plate 21 and the housing 4 so that the position of the movable plate 21 will not move randomly during use.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
